Back-up generator in Broken Hill tripped offline Monday 21st Oct, still offline Tuesday morning 22nd Oct 2024
At 16:41 (NEM time) on Monday 21st October the back-up generator in Broken Hill tripped – and is still offline on Tuesday morning 22nd October 2024.
What the last twenty years of the ESOO tells us about blackout predictions
After skimming through the last twenty editions of the ESOO over the past couple of days, Dan shares some thoughts about what has and hasn’t changed over the years.
Power outage in Western Australia (incl Kalgoorlie) from Wed 17th Jan 2024
A short record of a significant power outage in Western Australia in January 2024.
Stock up on candles?
Last Thursday (31st Aug 2023) the AEMO published the ESOO 2023, including forecasts of some possibility of unserved energy in Victoria and South Australia this coming summer 2023-24 (above the Interim Reliability Measure). Guest author Allan O’Neil takes a look.
With the 2023 ESOO report, different views about which USE figure should the AEMO have led with?
Here’s my view on whether Figure 2 should have preceded Figure 1 (with respect to projections of unserved energy … USE) in the 2023 ESOO.
AEMO releases 2023 ESOO on Thursday 31st August 2023 (Australia’s NEM is perched on the edge)
AEMO notes that ‘Australia’s NEM is perched on the edge’ in the 2023 ESOO, released today (Thu 31st Aug 2023)
Plenty of things went wrong in Queensland last Tuesday, but some very important things went right
Whilst there were many things that went wrong on Tuesday 25th May 2021 (last week), guest author Allan O’Neil highlights that there were at least 4 things that went right – contributing to a much less severe outcome than would otherwise have been the case.
Callide C Catastrophic Failure
Carl Daley from EnergyByte, provides more insight into the events of last Tuesday, which culminated in widespread blackouts throughout Queensland.
Case Study of 16:20 on 28th September 2016 (aggregate Raw Off-Target +894MW for Semi-Scheduled units)
This 8th case study in this series presents tabular results for all Semi-Scheduled DUIDs which were operational at the time of the SA System Black event.
Operating under siege
We take a look at challenges for AEMO in operating the system under the security threats posed by the ongoing bushfires …
Summer reliability back in the headlines
Guest author, Allan O’Neil, provides us an update today on what we can see about summer 2019-20 (in the physical market, and the financial market), now that it is only just around the corner.
ESOO Unboxing
Without resiling from last week’s criticism of how the headlines from AEMO’s 2019 Electricity Statement of Opportunities (ESOO) were communicated, it’d be churlish for me to fault the depth of disclosure and data sitting behind those results. Literally tens if…
ConfUSEd by the ESOO? You’re not alone.
I’d rather not add to the number of conspiracy theories in circulation, but I wonder if there’s a conspiracy to make understanding our electricity system in general, and its reliability in particular, as difficult as humanly possible. There’s no doubt…
Initial thoughts and questions about last Friday’s under-frequency load shedding in Great Britain
Some brief data gathering and analysis, primarily because I could not resist the exploration, of what might have happened with the load shedding in the electricity grid across England, Wales and Scotland on Friday last week.
Calculated level of inertia in the South Australian grid, supplied by synchronous generation plant
Last week’s notable under-frequency load shedding in Great Britain following what appears to be the loss of two generation units in quick succession prompts me to publish some of the analysis of aggregate levels of inertia supplied by synchronous generators in South Australia as part of the Generator Report Card.
Two different storm warnings in South Australia – one literal, and one metaphorical
Coincidentally this week it seems to me that we’re facing storm warnings on two different fronts – one literal (and much easier to prepare for), whilst the other one is metaphorical and operates at several different levels (and is much, much more difficult to manage).
Some very preliminary details of the possible causes of the Argentinian Blackout
Some very preliminary information (based on an internet search) about factors that might have contributed to the blackout in Argentina and neighbouring parts of South America this week.
Power station ‘trips’ are normal, but blackouts are not
Understanding the difference between blackouts, generator trips and intermittent generation and how these events are managed.
How does frequency regulation help avoid Blackouts?
What are the lessons about frequency regulation that can be learned from the SA blackout?
